Wisconsin -- Strangeness at Bong Park

The extensive UFO sightings here probably won't come as a surprise to regular visitors of the appropriately named Bong Park. On top of the UFOs, there have been numerous reports of alien abductions, ghostly apparitions, strange fogs, mysterious noises, and unexplainable lights. The park has a labyrinth of tunnels beneath it, leftover from when the area housed a military airbase, but access to these tunnels is forbidden by federal law.
